I receive mail from the Texas department of transportation asking my family to participate in a travel survey. the first number I received a call from about the survey letter I received was from Olathe, KS 913-254-4615 then the next day I received a call from the 432-248-0341 number. So I guess I'm just trying to figure out if this is a legitimate survey from the Texas Department of Transportation or if this is a scam?
